Select Layer... then Doodad... make sure you dont have a doodad selected to place it.. you can do that by clicking on a folder then clicking empty space on the palatte. click-drag over your doodad you want to remove and hit delete.
Guys just a heads up I am going to be shutting the site down soon. I am just waiting on the NUON people to decide whether they want to transfer forum data and keep the discord. My email is [email protected] for anyone that wants to keep in touch and I have a facebook too. I will make an official post later. Love you guys and will miss everyone!
